Aperture or LR4 for Mac
New to Mac and trying to decide between Lightroom and Aperture. Is there a difference in performance between the two on Mac? IOW, would one run more efficiently on Mac than the other?
Do the catalog file sizes tend to be larger in one v. the other?
Can anyone guesstimate how large a catalog/db file would be for about 75,000 photos in both applications?
Whichever I end up be would be using adobe camera raw + photoshop (CS6) + NIK + Topaz for PP.
